How about a turbonetics t78? Masterpower also has a t4 flanged 88 coming out soon. You can run runs on a MP t76 really. BTW, youre going to end up with a newer style computer and a 2 bar MAP, that 98 is just awful.

PT80 or PT88....that will do the job. GT4202 is to small...only a 74mm wheel.

You can do it with a 98 pcm. I have run almost 147 MPH in the 1/4 and 9.36 on mine. If you do decide to switch, don't switch to a newer stock pcm. Switch to aftermarket .
